The author of the article were Rizk, Hala F.; Ibrahim, Seham A.; El-Borai, Mohammed A.. The article conveys some information:
The 5-amino-4-heterylazo-3-phenyl-1H-pyrazoles (2a-d) were diazotized and coupled with malononitrile to give pyrazoloazo malononitrile which by heating in glacial acetic acid gave novel pyrazolo[5,1-c][1,2,4]triazine dyes (3a-d). Also, some diazopyrazolyl pyrazolone dyes (4a-h) were synthesized by diazotization of 2a-d and coupled with some pyrazolone derivatives The structure of the synthesized dyes was determined by elemental anal. and spectral data. All the synthesized compounds were applied as disperse dyes and their dyeing performance on polyester fabric was studied. The fastness and colorimetric properties were measured. The results revealed that the monoazo dyes have good fastness and good to moderate affinity to polyester fabric than diazo dyes. In addition, the synthesized dyes were screened for their antimicrobial activities against Staphylococcus aureus, Pseudomonas aeruginosa (Gram pos.), Bacillus subtitles, Escherichia coli (Gram neg.) and Candida albicans, Aspergillus niger (Fungi). The results revealed that most of the prepared dyes have high antibacterial activity. In the part of experimental materials, we found many familiar compounds, such as 1H-Imidazol-2-amine(cas: 7720-39-0Product Details of 7720-39-0)
1H-Imidazol-2-amine(cas: 7720-39-0) belongs to anime. Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Product Details of 7720-39-0
